Detailed Description
The following detailed description of the preferred embodiments of the invention, which is to be read in connection with the accompanying drawings, forms a part of this application, and together with the embodiments of the invention, serve to explain the principles of the invention and not to limit its scope.
It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another.
Example one
With reference to fig. 1 and 2, an embodiment of the present invention discloses an examine utensil and use flexible positioning mechanism, including positioning seat 1 and setting element 2. The locating seat 1 of this embodiment is provided with a pinhole, and this pinhole is used for aliging the locating hole of waiting to detect the part, makes things convenient for setting element 2 to treat to detect the part and fixes a position.
The positioning member 2 of the present embodiment includes a guiding section 21, a detecting section 22, a handle section 23 and an aperture detecting end 24. Wherein the guiding section 21 and the detecting section 22 are mainly used for positioning the part to be detected. Specifically, the guide section 21 is cylindrical, the detection section 22 is truncated cone-shaped, the guide section 21 is coaxially fixed on the small end surface of the detection section 22, and the guide section 21 is operatively inserted into the pin hole. When a part to be detected is placed on a tool, a positioning hole of the part is communicated with a pin hole formed in the positioning seat 1, the positioning piece 2 is inserted into the positioning hole of the part, the cylindrical guide section 21 of the positioning piece 2 penetrates through the positioning hole and then is inserted into the pin hole, the detection section 22 is partially inserted into the positioning hole, and the positioning piece 2 is stably inserted into the pin hole and is stably matched with the part until the diameter of the detection section 22 is the same as that of the positioning hole of the part; for parts with errors in the aperture of the positioning hole, the detection section 22 of the positioning piece 2 can be completely matched and connected with the positioning hole only by adjusting the depth of the positioning piece 2 in the pin hole without replacing a new positioning pin, so that the risk of losing the positioning pin is avoided, and the convenience and accuracy of detection of the detection tool are increased.
Further, the handle segment 23 is used to remove the positioning member 2 after the detection is completed, so as to release the fixed part. The handle segment 23 is then coaxially fixed to the large end face of the detection segment 22, so that the positioning member 2 can be pulled out by gripping the handle segment 23 with the hand. The aperture detection end 24 is coaxially fixed at one end of the handle section 23, which is far away from the detection section 22, and the diameter of the detection section 22 is the same as that of the large end face of the detection section 22. The diameter of the aperture detection end 24 is the diameter of the maximum allowable error of the pilot hole. That is, the size of the positioning hole is not allowed to pass through the hole diameter detecting end 24, the size of the positioning hole can be detected by the hole diameter detecting end 24, the size of the positioning hole is not allowed to pass through the hole diameter detecting end 24, and the size of the positioning hole is within the allowable range, which can be used as a reference for detecting the component. Similarly, the diameter of the smallest allowable error of the aperture of the positioning hole is the same as the small end face of the detection section 22, and therefore, when the size of the positioning hole is too small, the detection section 22 cannot be directly passed through for positioning.
Furthermore, the positioning seat 1 is further provided with an embedding hole, the embedding hole is also in a circular truncated cone shape, the pin hole is coaxially arranged on a small end face of the embedding hole, and the detection section 22 is partially inserted into the embedding hole in an operable manner. That is to say, when not detecting, can directly insert in pinhole and the nested hole through setting element 2, prevent that setting element 2 from losing.
Furthermore, the flexible positioning mechanism for the checking fixture further comprises a pressing portion 3, the pressing portion 3 comprises a supporting piece 31, a connecting plate 32 and a pressing frame 33, the supporting piece 31 is fixed on one side of the positioning seat 1, one end of the connecting plate 32 is fixedly connected with the supporting piece 31, the other end of the connecting plate 32 faces the positioning seat 1, and the pressing frame 33 is fixed on the other end of the connecting plate 32. In this embodiment, the pressing frame 33 is Y-shaped, the pressing frame 33 is divided into a long rod section and a fork head, the long rod section is fixed at the other end of the connecting plate 32, the fork head faces the positioning member 2, and the positioning member 2 is operably arranged in the middle of the fork head. Of course, the shape of the pressing frame 33 can also be set according to the requirements of the actual 3-position of the pressing part.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
